Hi all,

I'm using MATLAB 2015a in Linux Ubuntu 19.04.

My Matlab interface is a mess with the buttons of the interfaces.

Sometimes the editor buttons do not work, sometimes the buttons and clicking in the main matlab window do not work.

I get the following error when clicking in the Community button, for example:

Exception in thread "XPCOMMessageLoop" java.lang.UnsatisfiedLinkError: /usr/local/MATLAB/R2015a/sys/jxbrowser/glnxa64/xulrunner/xulrunner-linux-64/libxul.so: /lib/x86_64-linux-gnu/libcairo.so.2: undefined symbol: FT_Get_Var_Design_Coordinates

	at com.teamdev.jxbrowser.gecko.xpcom.AppShellXPCOMThread$b.run(Unknown Source)

Does anybody know how to solve such problem?

Hi , Finally I could solve this problem using this link:

https://podcloud.fr/podcast/tuxicoman/episode/undefined-symbol-ft-get-var-design-coordinates

The solution is very simple, rename libfreetype.so.6 in the matlabroot/bin/glnxa64

sudo mv matlabroot/bin/glnxa64/libfreetype.so.6  matlabroot/bin/glnxa64/BK_libfreetype.so.6

I have tested it with 3 version of Matlab and works for them

Best

I tried this and MATLAB simply crashed when I typed doc at the command line. R2018 in Ubuntu 20.

The error message I was trying to fix is shown below. This is what happens when I type doc at the command line.
